PLASTIC-MATERIAL-APPLYING DEVICE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed April 14, 1913. Serial No. 761,115.

To all whom it may concern 7 Be it known that I, ALBERT Spawn, a citizenof the United States, residing at Chester, in the county of Lake andState of South Dakota, have invented certain new and useful Improvementsin Plastic-MaterialApplying Devices, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to apparatus designed especially for use byglaziers for spreading putty and stone masons for spreading mortar intuck pointing or beading An object of the invention is to provide adevice of this character including a receptacle for the material andnovel means combined with the receptacle for forcing the material outthrough the receptacle outlet, such means being adapted to be soadjusted that the entire contents of the receptacle can be effectivelyforced out before refilling the receptacle.

A further object is to provide an extremely simple and durable device ofthis character which will be formed of a few simple parts that will noteasily get out of order.

With the above objects in view the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claims.

In the accompanying drawing illustrating this invention: Figure 1 is aside elevation of the invention. Fig. 2 is a plan view. Fig. 3 is avertical sectional view. Fig. 4: is a detail perspective view of thespout.

Referring now to the drawing in which like characters of referencedesignate similar parts, 10 designates a cylindrical receptacle which isclosed at the bottom and open at the top and is provided exteriorly withscrew threads 11 from top to bottom. A curved spout 12 opens through thecenter of the bottom, this spout being cut away obliquely at thedelivery end as shown at 13 to facilitate the discharge of the materialas usual in devices of this character. A spreading blade 14 is securedto the tip of the spout by means of a bolt 15 or otherwise, it beingunderstood that blades of various sizes and shapes may be substitutedfor the blade illustrated without departing from the spirit of theinvention. The receptacle is designed to contain plastic material suchas putty, mortar, or the like, and for forcing this material out throughthe spout the following mechanism is employed: A flat band 16 isprovided interiorly with screw threads 17 which engage with the screwthreads on the exterior of the receptacle, the band being thus capableof being advanced to any desired position longitudinally of thereceptacle, such adjustment of the band being facilitated by means of ahandle 18 that is integral with the band, which handle forms means forrotating the band and thus positioning the same at any desired place onthe rece tacle. Diametrically opposite from the hand le the band isformed with an integral eye 19. An eye bolt 20 is passed through the eye19 and extends vertically upward beyond the top of the receptacle, therebeing a nut 21 disposed on the eye bolt below the eye 19 which contactswith the latter and holds the eye bolt against withdrawal. An operatinglever 22 is passed through the eye 23 of the eye bolt and is then headedup as shown at 24:. A post 25 is threaded into the operating lever andis positioned above the center of the receptacle, this post terminatingbelow the lever in a head 26. A plunger in the nature of a disk 27 worksin the receptacle, the plunger having a stem 28 which is equipped at theupper end with a socket 29 that loosely receives the head 26.

In operating the device, the handle 18 and the operating lever aregrasped and the operating lever forced toward the handle with aresultant urging of the plunger against the body of plastic material inthe receptacle whereby the material is forced out through the spout and,if required, the blade 14 may be employed to spread the material afterthe same has been properly ejected. As the body of the material in thereceptacle becomes depleted to such an extent that the effectiveness ofthe plunger is impaired, the band 16 is rotated until it assumes a lowerposition on the receptacle, carrying down with it the fulcrum of theoperating lever 2'. e. the eye bolt 20, whereby the plunger is againpositioned to effectively operate upon the body of the material. Thisoperation may be repeated until the band is positioned at the bottomedge of the receptacle in which position the plunger will operateeffectively to force out the remaining material from the receptacle.

From the above description it will be seen that I have provided anextremely simple and durable device of the character described, Whichdevice is formed of a few parts that Will not easily get out of order.

What is claimed, is

1. A device of the character described including a receptacle having adischarge opening, a plunger mounted for recurrent movement within saidreceptacle, an operating lever connected to said plunger, a memberthreaded upon the receptacle and capable of GHClWlSG adjustment thereonwhen axially moved, and a fulcrum for said lever carried by such member.

2. A device of the character described including a receptacle having adischarging opening, a plunger mounted for recurrent movement Withinsaid receptacle, an operating lever connected to said plunger, a band inthreaded engagement With said receptacle, and a fulcrum member for thelever connected to and supported by said band, the connection betweenthe band and receptacle permitting said band being advanced or retractedlongitudinally of said receptacle whereby to vary the position of saidfulcrum relatively to said receptacle.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
